Securities Compliance Counsel

Amendment clarifies reporting responsibilities under SEC Release No. 34-39538.

The filing explains that certain Vanguard subsidiaries now report beneficial ownership separately, and The Vanguard Group 'no longer has, or is deemed to have,' beneficial ownership over those subsidiary-held securities. The signature block shows the filing was executed on 03/27/2026.

Because this is a Schedule 13G/A disclosure of ownership changes, it is procedural: future subsidiary Schedule 13 filings will contain the actual subsidiary-level positions.
